AVC/MPEG-2/MPEG-4/DivX®/VC-1 HD Digital Video SoC for Satellite, IP and Cable
The BCM7404 is a high-definition satellite, cable, and IP set-top box solution offering integrated AVC (H.264/MPEG-4 Part 10), MPEG-2, DivX, MPEG-4 Part 2 SD SP/ASP, and VC-1 video decoding technology. It combines a data transport processor, high-definition AVC/MPEG-2/MPEG-4/DivX/VC-1 video decoder, advanced-audio decoder, 2D graphics processing, high-quality video scaling and motion adaptive deinterlacing, six video DACs, stereo high-fidelity audio DACs, a MIPS32/MIPS16e class CPU, and a peripheral control unit providing a variety of set-top box control functions.
The MPEG-2 DVB-compliant transport stream/PES parser and demultiplexer is capable of simultaneously processing 256 PIDs via 128 PID channels in up to five independent external transport stream inputs and two internal playback channels. All 128 PID channels can be used by PCR processing, message filter, and for output via the high-speed transport or remux module. The transport provides 1DES/3DES/DVB/Multi2/AES descrambling support. A memory-to-memory DMA security module may be programmed for supporting AES/1DES/3DES/CSS/CPRM/CPPM/DTCP copy protection algorithms/standards. The BCM7404 features the Broadcom secure processor providing secure key generation, management, and protection.
